Title: Process for the recovery of oil from shale
Inventor: MCCARTHY DAVID JOHN
IPC: C10B49/16
Filed: 1982-09-30
Abstract: A continuous process for recovery of oil and energy from oil shale. Particulate oil shale (1) is mixed with hot particulate heat carrier (2) containing free lime and retorted at conventional retorting temperatures in the presence of a purge gas (3). The purge gas comprises compounds which can react with the free lime. The mixture of spent shale and heat carrier solids (5) is separated from the product gas and vapours (4) and the solids are combusted in air (6), (7) with the optional addition of materials (8) to control the free lime content of the ash product from combustion. A stream of particles (12), extracted from the combustor is separated into a larger portion of coarser hot shale ash which is recirculated to the retorting zone as heat carrier. A smaller stream (15) is disposed of as waste after separating the energy (17) therefrom. The sensible and chemical heat from the waste solids and the sensible heat from the gases leaving the combustion zone, is recovered (J).

IPC: C12N9/36
Filed: 1988-04-19
Abstract: The method is applied in the food and pharmaceutical industry. With it, a lysosime of high capacity and cleanness is derived via a simplified technology, lower duration of process, which avoids the lasting stages of recrystalization for purification of the product without adding pH correctors. The method: a lowacid macroporose carboxyle cathionite resin is treated with a homogeneous egg white with a natural pH of 9.0 to 11.0 under the continuous mixing at a speed of between 40 to 50 revolutions/minute for 60 minutes. The derived enzyme solution after eluation is subject to a thermic treatment at a temperature of 60 degrees C for 30 minutes at a continuous mixing. Before the temperature processing pH of the enzyme solution is lowered to about 3.5.

Title: Fluorescent indicator dyes for alkali metal cations
Inventor: TSIEN ROGER Y
IPC: C07D273/00
Filed: 1989-11-14
Abstract: The invention discloses fluorescent chelator compounds that are especially useful to monitor and measure cytosolic concentrations of alkali metal cations such as Na+, K+, and Li+.  Particularly, the present invention relates to an aza-crown ether of the formula:               wherein the substituents are as defined in the specification.  The crown ethers may or may not have substituent groups attached to the core carbons, but will always contain at least one core nitrogen.  The crown ethers are linked via the core nitrogen(s) to at least one fluorophore that contains an additional heteroaromatic liganding center.  In the currently preferred dye, SBFI, the core compound is crown ether 1,7-diaza-4,10,13-trioxacyclopentadecane and the heteroaromatic fluorophores are benzofurans that are linked to isophthalate groups. Selectivities for Na+ over K+ of about 20 are observed, resulting in effective dissociation constants for Na+ of about 20mM against a background of 120 mM K+.  Increasing [Na+] increases the ratio of excitation efficiency at 330-345 nm to that at 370-390 nm with emission collected at 450-550 nm, so that ratio fluorometry and imaging work at the same wavelengths as used with the well-known Ca2+ indicator fura-2.  If the macrocyclic ring is increased in size to a 1,10-diaza-4,7,13,16- tetraoxacyclooctadecane, the chelators become selective for K+ over Na+.  If the ring is decreased in size, for example to a 1,7-diaza-4, 10-dioxacyclododecane, the chelators become selective for Li~ over Na+.

Abstract: This invention describes a wooden wall construction and method of making the same for a wooden building.  In particular, this invention provides for a wall construction which reduces the problem of gap formation between adjacent timber members caused by factors such as wood shrinkage and foundation movement.          Upright timber members are provided with vertical grooves aligned so as to receive extensions from the ends of stacked horizontal timber members of uniform length.  With the exception of the lower-most horizontal timber members, these members are not secured to the upright timber members so that they can move upwards or downwards within the grooves to accommodate shrinkage and settling factors.  Preferably when settling of the horizontal timber members has occurred to a significant extent, the roof structure will then rest on the upright members.
